From: WANG Cong Date: Thu, 24 Jul 2008 04:28:49 +0000 (-0700) Subject: UML: make several more things static X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=99764fa4ceeecba8b9e0a8a5565b418a2e94f83b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git UML: make several more things static - Make some variables and functions static, since they don't need to be global. - Remove an unused function - arch/um/kernel/time.c::sched_clock(). - Clean the style a bit as complained by checkpatch.pl.
